First I would suggest.... Work out what you need to earn to live.... current outgoings could be the make or break for anyone starting.... Do you have a slush fund to tide you over whilst you build?
Be wary though, there is a world of difference between working for enough to live and earning enough to live

Building a well priced and established round with good payers is not an easy task, granted the work itself is not exactly rocket science but getting to a stage where you can meet all your financial commitments without the hassles of constant late paying customers is 'nirvana' we all strive for.
Obviously I and others here do not know your individual situation (nor need to

perhaps if you do not have a slush-fund you could start Saturdays then go part-time... who knows what options may or may not suit... perhaps you could buy/rent a round.
If you do go down the wfp route... as with all things there are budget cars and then there are supercars the same can be said for wfp equipment.... you can make it as simple/complex >>> cheap/expensive as you want or failing that get yours ladders out and go trad as you have previously.... again all upto you.... But the best advice I have seen here is.... find out what your local market is paying.... I can tell you what is right where I am but thats going to be naff all use to you.
Again good luck starting.... Remember the game is simple.... Get 1 job, get another, get another...so on and so forth...clean them and then repeat.
Find 1 job at a time and don't accept rejection too personally....
tip...when you go out looking for work....obviously dress smart, never admit you are just starting and carry yourself like you have been in the game for years.... no-one knows what you are...act confident, be fair, polite and courteous..... a rejection is another step to success.... its a numbers game, once you are established.... work will find you... honestly it will - Yeah I thought this was complete and utter pooh when someone told me when I started.
